Product details
Luoyang Golden Egret Geotools Co.,LTD-Tungsten Carbide Powder GP12-19
 
These tungsten carbides powder, such as GP12-19, are spheroidal powders for thermal spraying containing 88% tungsten carbide as a hard material and a cobalt matrix that functions as a binder material for the carbide particles. This tungsten carbide coating is agglomerated and sintered powders. Coatings of these materials are harder compared to coatings of 83WC-17Co as a result of higher tungsten carbide levels. Coatings are resistant to sliding wear, hammer (impact) wear, abrasion and fretting at temperatures up to 500 °C (930 °F) in non-corrosive media.
 
Coatings that contain tungsten carbide protect substrates from the effects of fretting, abrasive grains, particle erosion, cavitation and dynamic contact with hard surfaces. In particular, these materials can be used for abrasion-resistant coatings in dry, non-corrosive environments at temperatures up to 500 °C (930 °F). HVOF and APS (using a TriplexPro™ series gun) coatings of these materials are dense and show good bond strength. 1.1 Typical Uses and Applications Tungsten carbide – 12 cobalt materials from Oerlikon Metco are among the best-known thermal spray powders for use in wear applications at service temperatures below 500 °C (930 °F) in non-corrosive media.
 
Typical applications include: n Steel rolls n Sink rolls in zinc pots n Corrugating rollers n Agricultural rasp bars n Exhaust fans n Conveyor screws n Sucker rod couplings n Thread bars n Pump housings n Impeller shaft
